Other than diarrhea, are there serious illnesses caused by STEC strains of E. coli?

Most cases of E. coli infections are mild and do not cause a serious health risk. Cases resolve on their own with rest and drinking plenty of fluids. However, some strains can cause severe symptoms and even life-threatening complications, such as hemolytic uremic syndrome, which can lead to kidney failure and death.
